Do you have a serial setup for both grub and Xen, and if so can you paste the full bootlog until you hit the error? > > I have found a workaround to fix my issue - remove option --nounzip from > > initrd loading line in grub configuration file /etc/grub.d/20_linux_xen > > > > - module2 --nounzip /boot/initrd.img-4.19.0-5-amd64 > > + module2 /boot/initrd.img-4.19.0-5-amd64 > > > > I'm not sure there is issue in config, maybe I did something wrong. > > So in this case please explain what is correct behavior ? > > I'm using Xen and things seem to work fine for me (without removing > --nounzip); my Xen system doesn't use UEFI, though. > > I'm CCing a few folks who've contributed to GRUB's Xen support in one > way or another in the recent past; hopefully at least one of them can > help here? That's certainly weird, I'm using grub2 with UEFI (the packages with the multiboot2 backports provided by cjwatson for stretch) and --nounzip seems to work just fine there. Maybe you can give a try to the packages from stretch in order to make sure it's grub2 the culprit of the issues you are seeing? Roger.
